Herein, an interesting palladium-catalyzed procedure for the direct carbonylative thiomethylation of aromatic amine derivatives with 4-methylthio-2-butanone is developed. Using 4-methylthio-2-butanone as (methylthio) transfer agent, a variety of corresponding thioesters are obtained with moderate to good yields under base-free condition. In addition, good functional group tolerance can be observed.

An interesting procedure for thioester synthesis via nickel-catalyzed thiocarbonylation of arylboronic acid with sulfonyl chlorides as the sulfur source has been explored. Using Mo(CO)6 as a solid CO surrogate and reductant, a broad range of thioesters were obtained in moderate to good yields with good functional group tolerance.

Poly(3,4-dimethyl-5-vinylthiazolium) was synthesized from 3,4-dimethyl-5-vinylthiazole through free radical polymerization and was examined as polymer precatalysts in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) for the thioesterification of aldehydes with thiols. The poly(5-vinylthiazolium)/DBU had excellent catalytic activity and could be reused 10 times without a considerable loss of activity. To S-um up: Poly(3,4-dimethyl-5-vinylthiazolium) is examined as a polymer precatalyst in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) for the thioesterification of aldehydes with thiols. The poly(5-vinylthiazolium)/DBU system shows excellent catalytic activity and can be reused 10 times without a considerable loss of activity.

A new and simple route for the synthesis of thioesters starting from carboxylic acids and alcohols is reported by using tetrathiomolybdate as the key sulfur transfer reagent, Triphenylphosphane and N-bromosuccinimide were used for the activation of the ca
Montmorillonite K 10-catalyzed regioselective addition of thiols and thiobenzoic acids onto olefins: An efficient synthesis of dithiocarboxylic esters

, p. 3791 - 3794 (2007/10/03)
The addition of thiols and thiobenzoic acids onto olefins proceeded regioselectively in a Markovnikov manner in the presence of Montmorillonite K 10 (Mont K 10) clay as the catalyst to afford thioethers and thiocarboxylic S-esters, while high selectivity to anti-Markovnikov products was realized in the absence of any catalyst. Treatment of the esters with Lawesson's reagent provided the corresponding dithiocarboxylic esters in high yields.
